This compelling comparative chart demonstrates that the “coming of the Son of Man” in both the Olivet Discourse and Mathew 16:27-28 refers to the second coming of Christ in fulfillment of both Old and New Testament prophecy, specifically, Daniel 7 and Hebrews 9:28. What this means is that the second coming of Christ was fulfilled at the judgment of Jerusalem in AD70, when the enemies of Christ were destroyed, and the saints received the kingdom, that is, their complete salvation (redemption)
